摘要： PURPOSE:To provide a multicolor mood lighting system which is excellent in luminous efficiency and whose service life is long and in which the replacement of a lamp is easy by arranging plural paired electrodes in an electric discharge container holding body, sealing up an electric discharge medium in an electric discharge container, and applying a phosphor to the inner peripheral wall. CONSTITUTION:When high frequency voltage is impressed between respective plane-like electrodes 11a, 11b-13a, 13b, voltage is supplied to an electric discharge medium in an electric discharge container 5 through glass of a dielectric in contact with them or adjacent to them, so that electric discharge is caused. UV radiation generated by this discharge excites phosphor 6a-6c formed on the inner wall of the container 5, and emits red color, blue color, and green color visible beams each having a wave length characteristic of the phosphor from an upper part, an intermediate part and a lower part, and those are outputted from a light output part 7. A light flux is changed according to a voltage value of the impressed high frequency voltage. In this constitution, structure can be simplified and the replacement of a lamp only requires to insert o fit the lamp into a discharge container holding body 8, so that a multicolor mood lighting system, which is excellent in luminous efficiency and whose service life is long and in which the replacement of the lamp is easy, can be provided.

摘要： PURPOSE:To improve the image quality of a large sized color display by arranging a prescribed electrode in the half circumferential lengthwise direction of a cylindrical dielectric container and arranging the correponding fluorecent body layer contiguously with the irradiation part of a fluorescent lamp which emits light, adjusting direction. CONSTITUTION:When each voltage is applied to electrodes 5Aa and 5Ab having each prescribed width L from a controller, the voltage is aupplied to the xenon in a bulb 2 through the glass of a dielectric body, and electric discharge occurs. The generated ultraviolet ray excites a fluorescent body layer 3A and is converted to the visible lights of three primary colors R, G and B, and irradiated from a light irradiation part 4. Since, in the irradiation part 4, each of R, G, and B is arranged contiguously, and an image element E is constituted, the light color is synthesized by controlling the voltage application to each dlectrode 5Aa, 5Ab, and a desired color light is generated and irradiated from the image element E. Accordingly, if a device is constituted of the image element E, a color image can be displayed distinctly.

摘要： PURPOSE:To illuminate a desired surface such as a desk top surface or a working surface top uniformly with directivity without giving a sense of glare by arranging a surface emissive illumination unit along the reverse of a shelf plate of a book shelf arranged in a study desk body. CONSTITUTION:A surface emissive illumination unit 5A is composed of a highly bright small tube fluorescent lamp 5a, a light conductive plate 5b and a reflecting plate 5c, and this unit 5A is arranged in an optical position along the reverse U of a shelf plate 4. When the lamp 5a is lit up, the whole light of the lamp 5a is projected convergently on the light incident edge surface (a) of the plate 5b by means of the plate 5c. This light is transmitted inside of respective light conductive plates P while repeating total reflection toward the light outgoing edge surface (b), and is projected uniformly on the plate 5c from the side edges of the respective plates P. Next, the light is reflected uniformly in the prescribed direction from the surface S1-S5 of the plate 5c with directivity in a surface emissive condition, and since the light illuminates a desired desk top surface of a desk body uniformly and effective by means of light distribution with sharp directivity, the direct light never enter eyes, so that fatigue caused by glare is hardly felt.

摘要： PURPOSE:To obtain a high-quality picture on a picture display panel where trio picture elements constituted of three pixels, which are red, green and blue, are arranged in a grating shape. CONSTITUTION:The trio picture element 1 is constituted so that the length of one side of the picture element 1 which constitutes the picture display panel may be the length of the long side of the blue pixel and the length of the other side of the picture element 1 may be the sum of the length of the long side of the red or the green pixel and the length of the short side of the blue pixel, and the ratio of the length of the short side of the picture element 1 to the length of the long side thereof is set at >=0.85. Thus, the vertical and horizontal resolution of a display screen is equalized, a non light emission part on the display screen is eliminated at the same time, and the good-quality image is obtained.

摘要： PURPOSE:To allow a mirror to reflect an image having a proper lightness by installing an illumination unit of surface light emission type over the mirror in horizontally laid arrangement, and accomplishing an illumination which is provided with butt-wing light distribution having excellent directionality and in which no glaring will be generated. CONSTITUTION:The light from a fluorescent lamp 3a is projected concentratedly by a reflex plate 3c onto the light incident surface (a) of a photo-conductive element 3b. By the same princple as optical fiber, it is led in each photo- conductive plate P to the light emitting surface (b) while making whole reflexion repeatedly, and is reflected in the condition with surface light emission by the reflex surfaces S1-S5 of the reflex plate 3c evenly with a certain directionality, and a person confronting the mirror body 2 is thereby illuminated effectively with a uniform bright light with less damping. This allows the person to carry out makeup or shaving properly, and the person is free from feeling any fatigue due to glares because no direct beam of fluorescent lamp 3a will come into the eyes. Also the appearance of the mirror can be improved.

摘要： PURPOSE:To enable face illumination with only one point light source by concentrically forming a light guide panel, and providing a lamp at the center portion of the panel. CONSTITUTION:Light guide plates 12 of different size are stacked to form a light guide panel 13. The structure of the light guide panel 13 is such that the plural light guide plates 12 in the form of concentric circles with sequentially varying radii are stacked one after another with a space provided at the center portion of the plates to accommodate a lamp 11. A reflecting plate 15 is provided for reflecting light transmitted through the light guide panel 13. Incident light 14 emitted from the lamp 11 is transferred to the inside of the light guide panel 13 and reflected by the reflecting plate 15 and emitted to the outside as a uniform face light source. Simple and compact face illumination can thus be obtained simply by use of one light source as a point light source.

摘要： PURPOSE:To eliminate a need for pulling the tip end of a hose from the connector while an user bends himself after he has removed the hose while going around aside by providing the handle of a main body with an auxiliary suction port, and thereby concurrently providing an air duct switching means which switches the auxiliary suction port and a main suction port interchangeably over to a duct collecting section. CONSTITUTION:After cleaning the center section of a room has been done, cleaning the corners is generally started next. When narrow gaps such as a gap between each furniture and the wall are cleaned, the lock between a handle pipe 4 and a main body 1 is released first. This thereby permits the handle pipe 4 to be pulled up out of the main body 1 together with a flexible hose 28. In this case, an operating handle 5 at the upper section of the handle pipe 4 is replaced with suction accessaries such as a gap nozzle, a round brush and the like. The switching valve 27 of an air duct switching mechanism is switched over with a switch 31 operated, the handle pipe 4 is thereby connected to a dust collecting section 21 through the auxiliary air duct 26.
